Questions
- Are these YouTube tools really free?
- Most are free with no account: the research tools, every generator and the size checkers. The deeper AI checks (Packaging Check, Hook Analyzer, Video Analyzer) use credits; a free account starts with 15.
- Where does the data come from?
- Public YouTube data through the YouTube Data API. Outlier scores divide a video's views by the median views of its channel's recent uploads. You never connect your channel.
- Do the AI tools invent numbers or results?
- They're instructed not to. Anything that needs your real results, numbers or experience is left in [brackets] for you to fill in.
- How is this different from vidIQ or TubeBuddy?
- HookSignals focuses on the decisions before you publish — what to make and how to package it — using videos that beat their own channel as evidence, rather than keyword scores or channel management.
